Abstract:
According to the present invention, the size of a droplet ejected to a target area is minimized to obtain high printing resolution, and effects of attraction and adhesive forces acting between a nozzle and air resistance can be minimized so that the target area is finely controlled to obtain high printing precision. An inkjet printing apparatus according to the present invention includes an ejecting device ejecting a droplet of a solution to a target area; and a light irradiating device irradiating light onto the droplet at an acute angle with respect to a line going through the ejecting device and the target area to heat and evaporate a part of the droplet before the ejected droplet reaches the target area, so that the droplet is accelerated along the line.

Abstract:
The invention relates to a high-dielectric constant metal/ceramic/polymer composite material and a method for producing an embedded capacitor.As ceramic particles having a relatively small size are bound to the surface of metal particles having a relatively large size by mixing, the occurrence of percolation can be prevented without coating the metal particles, and at the same time, the capacitance of an embedded capacitor can be increased. In addition, a process for coating the surface of the metal particles can be omitted, thus contributing to the simplification of the overall preparation procedure.
Abstract:
A method of providing information and a method of providing a push mode service. The method includes: obtaining from a client a priority in relation to a service mode desired by the client, determining whether or not a push mode service is to be provided continuously according to priority, and providing a service according to the determination. While a service is used in a pull mode, according to the priority selected by the client, reception of a push mode service is refused or the pull mode service is stopped and switched to a push mode so that important information can be received.

The electric energy storage device including a capacitor and a secondary battery combined in series is provided. When the capacitor of the electric energy storage device is an electric double layer capacitor, the capacitor is used to the voltage of OV or less to increase an available energy usage. When this energy storage device is used as a power in a place where a rapid keeping and repairing is difficult such as out in the fields including in the mountain, at the sea, on the road, the cost for keeping and repairing can be largely reduced.
Abstract:
The present invention provides a closed loop fat transplantation system newly designed to aspirate a fat, to handle it without receptacle transfer and to transplant it into the human body, which is composed of a fat transplantation receptacle(hereinafter referred as FT receptacle) and an exterior mechanical pressurization/decompression means. The said FT receptacle includes a vertical hem portion where joining selectively individual syringe needle or cannelae, a cylinder-shaped receptacle to aspirate and store fat, a piston head to parcel the said cylinder-shaped receptacle into front fat storing space and rear pressurization/decompression space. The said pressurization/decompression means can give positive/negative pressure to the fat storing space through the piston head of the said FT receptacle and it has a structure separable from the said FT receptacle. Accordingly fat transplantation can be performed without receptacle transfer using the same FT receptacle extracting fat from patient's body giving negative pressure through the piston head to the fat storing space.
Abstract:
An electric energy storage system having a novel structure which exhibits a ling cycle life, rapid charging-discharging characteristics and a high energy density. The electric energy storage system comprises: an anode comprised of a first material that performs interalation-deintercalation of cation as an anode active material; a cathode comprised of a second material that may form an electric doublelayer with anion as a cathode active materials; and a electrolyte including lithium salt, the electrolyte including the cation and anion. Due to a high difference between anode and cathode in capacity to store the electric energy, most electrochemical impact that occurs in the process of intercalation-deintercalation of electric energy is absorbed into cathode and active material used for anode is activated carbon having a very high resistance to electrochemical and structural impact, so that its operation life is elongated and it has rapid charging-discharging characteristics. The electric energy storage system can complement the defects of a conventional technology.
Abstract:
A reciprocating saw for use in oral cavity bone cutting operations, including a handle, a neck extended from the handle, and a head case to be coupled to an end of the neck. A motor is mounted inside of the handle. A slider shaft is mounted inside of the head case to form an angle of approximately 90° with respect to the neck, and moves in a straight linear reciprocating direction along the slider shaft which is mounted. The slider and the motor are coupled by a power linkage device for converting rotational power of the motor to a straight linear reciprocating movement of slider whereby a direction of the bone cutting operation performed by a saw member or a file member attached to the slider forms an angle of approximately 90° with respect to an approach direction of the handle, and provides a significantly high efficiency in bone cutting operations since the bone cutting operation can be performed in a narrow space, while ensuring a wide field of view. In addition, an upper cut off portion of a mandible to which a conventional saw has a difficulty in approaching, can be easily approached and cut off.

Abstract:
A metal oxide electrode for a supercapacitor and a manufacturing method thereof are disclosed. Potassium permanganate is absorbed on a conductive material, such as carbon or activated carbon, and mixed with a solution including manganese acetate so as to form amorphous manganese oxide. Amorphous manganese oxide powder is grounded to a powder which is mixed with binder to form an electrode having a predetermined shape. The electrode reduces equivalent serial resistance and enhances high frequency characteristics since the contact area and the adhesion strength between the manganese oxide and the conductive carbon are improved. Also, the electrode has high capacitance suitable for a supercapacitor, which is manufactured therefrom at a greatly reduced cost.
